I sent a cover of important urgent sample to pp international, kadirvedu, chennai 66, on friday 17 july at triplicane. They promised delivery on saturday. But nodelivey.. On tracking it reached puzhal on 20 8.15am, why this delay?

I was repeatedly trying to contact mr. Muthu of puahal but he was not answering,

Till the time of writing this msg (21.7.20 8.30am) it has not reached the client. I have lost 1lakh order.
